Canada Caregiver benefit for several years

[thankyou]

Hello I am trying to get the Canada care giver tax credit for my daughter 18 years or older for the years 2017 2018 2019 and 2020 I do not have an spouse /common law partner I am single

My question is in what exact line(s) of schedule 5 should I claim the tax credit

My understanding is that for the years 2017

This should be claimed in line

Line 307 – Canada caregiver amount for other infirm dependants age 18 or older

not

Line 304 – Canada caregiver amount for spouse or common-law partner, or your eligible dependant age 18 or older

------

And that lines

Line 303 – Spouse or common-law partner amount Line 303 – Spouse or common-law partner amount

And line

Line 305 – Amount for an eligible dependant

Should not  be modified

Same for the year 2018

-----

For the year 2019

This should be claimed in line

Line 30450 – Canada caregiver amount for other infirm dependants age 18 or older

not          

Line 30400 – Amount for an eligible dependant

Line 30425 – Canada caregiver amount for spouse or common-law partner, or your eligible dependant age 18 or older

And that

Line 30300 – Spouse or common-law partner amount

Should not be modified

I would really appreciate some input as even the  cra is giving me contradicting advice regarding this

My income should not have an impact on how this form is filled, am I right

Also for this to be claimed in the year 2020 the one thing that has to be done is to add a schedule 5 am I correct

 

[thankyou]

are you sure
2017-2018
 it clearly states in line 304
Complete this calculation only if you entered $2,150 on line 5109 or line 5110 of this schedule for a person whose net income is between $6,902 and $23,046.
and line 5110 is part of Line 303 – Spouse or common-law partner amount , which is not applicable to me since i dont have an spouse 
2019-2020
line 30450
You can claim an amount for each dependent who meets all the following conditions. They: • were dependent on you because of an impairment in physical or mental functions • were 18 years of age or older • were your or your spouse’s or common-law partner’s child
whereas the other lines have to do  with partner /spouse
line 30300 30400 30425 all mentioned here 
If you can claim an amount for your spouse or common-law partner on line 30300 of your return or for an eligible dependant 18 years of age or older on line 30400 of your return, you may be able to claim an amount on line 30425 of your return. However, you must first claim the amount of $2,273 in calculating either the amount on line 30300 or the amount on line 30400, whichever applies.
