I'm needing to amend my 2023 tax form and to be able to do it electronically TurboTax is telling me I would've had to file my 1040 on TurboTax. Well I did file on here and it was accepted but it didn't save as a TurboTax file in the program but as a PDF on my computer. How do I fix this to save me from having to print and mail it out?
