I filed federal and state tax returns a month ago but just got a 'Corrected" 1099R. The only change is that the original 1099R had a box checked that said "Total distribution" and the corrected form does not have this box checked. The 2019 distribution was only part of the account so I think the corrected form is right. I hadn't noticed this when I filed. Do I need to change my return or do anything about this?
