Amending 2020 Federal and State returns

I use TurboTax desktop (CD)version for my filing. I have just e-filed both  my 2020 federal and state (MD) returns, both have been accepted, and a tax refund will be coming back on both. After e-filing, I received a 1099R that was not included in the original filing. I have adjusted my return to add the 1099R in order to amend the return. The amended return will have me paying slightly more in federal tax ($51) and slightly less in state tax ($99).

I reentered my TurboTax desktop, selected amend for my return, followed the steps and received a note saying that the IRS is still working on finishing up the amended return section (Form 1040X) for 2020. Any suggestions on how to proceed?
