My grandmother has dementia. I was asked by my parents to file her tax return this year because I have the ability to do so with multiple filings in my version of Turbo Tax. However, I am not my grandmother's power of attorney...my uncle is her POA. I saw on IRS.gov that there are special forms that can be used to designate a POA or Representative, and I was not sure if I need to do anything with those.
Is there anything special that I (or my uncle) need to do in this situation before e-filing on her behalf?
