Thanks for your continued patience.. OK I tried that, entering two different purchases and sales of the same condo, with the first sale listed as a principal residence sale 2006 to 2014, and the second with No as the answer to the PR question, 2014 to 2021. Again the program will allow electronic filing, but again a warning message, this one saying the disposition date is before the minimum date (which should be in 2021)
The date value for this field is before the required minimum.
The date should be '01-01-2021' or after, you have entered '21-04-2014'. Click here to review your data.
So I am just not sure which of these warnings is more of a red flag to CRA, it seems both indicate a missing deemed disposition that was not filed in 2014, but the second method (this one) more clearly states the amends I am trying to make...
