Cannot file 2025 amended return - Continue Button does not advance to the next screen

I have filed my 2025 Federal and State taxes and received confirmation that both were accepted.  Then I realized I'd missed an investment account.  I have gone into the software (desktop version) and clicked on Amend, added the information and process through the checks.  When I get to the screen that says "We Recommend E-filing Your Federal Return", I click Continue, and move on to "We Recommend E-filing your State Return".  Clicking "Continue" here, just takes me right back to the "We Recommend E-filing Your Federal Return" screen.  Also, when looking at my files, I don't see that the 1040 form has changed to an amended version.

Do I need to wait for some sort of Federal/State processing before filing the amendment?
