I am filing my grandson's first individual federal and state return. His parents' tax preparer filed their return for 2020 erroneously claiming him as a dependent. When I filed his CORRECT 2020 return it was rejected. His parents' AMENDED 2020 return was then filed. IT HAS NOT YET BEEN ACCEPTED BY THE IRS. I also filed a time extension on his initial 2020 return until October 15, 2021. What do I need to do, considering the IRS's delay in accepting his parents' amended return?
