Filing a federal 1040-sr for my mother who passed away in 2020. What additional forms do I need to include with the return?

I am sorry for your loss.

You may be required to file Form 1310 if you are claiming a refund on her behalf.

See https://www.irs.gov/pub/irs-pdf/f1310.pdf

Otherwise, the forms will depend on the type of income she received prior to the date on which she passed.
