I submitted my federal and state tax returns yesterday. Both the feds and state have accepted them. I would like to do some what-if scenarios on a copy of my completed returns to make sure I'm having enough withheld in a couple of income sources. I'm retired and on disability this year, so I need to dial in my withholdings.
Can I safely copy me completed return to a different named file and run my what-ifs on the copy without impacting the original?
