Form 2848 (POA) line 3 "tax form number"

I plan to file a tax form for my parent, and I am trying to fill out form 2848 to get power of attorney to represent her to the IRS. I want to prepare and file annual taxes for her for 2024 and going forward. She will file Form 1040 or 1040-SR.

 

Is it enough to just declare "Income" and "1040" in line 3?

 

Do I need to specify Form 4868 here also, in case I want an extension?  Are there other forms that I should be specifying here aside from 1040, just in case?
