Downloading data from CRA and/or from Revenu Quebec?

[Mado]

I live in Quebec. If I download data from CRA there is information missing (ex. instalments paid to Revenu Quebec). If I download data from Revenu Quebec there is information missing from CRA (ex. instalments paid to CRA). Will it mess up things if I download from both?

Yes, it will. Download only from the CRA, and then manually add the missing RQ data.  Most Revenue Quebec fields will populate correctly with the CRA download except for withheld Quebec income  tax and taxable benefits added to earned income. If you log in to your Revenue Quebec workspace, you can see exactly what information is available and make note of it. Then it is just a matter of manually adding to the correct fields in the CRA slips.
