I have the same issue, unable to get past the last check in filing. Spouse's employer made a contribution for the first payroll in January 2024 even though he became covered by Medicare in December 2023. I verified that we did not overcontribute in 2023 and the 2023 question is answered as No, but I am still not able to move past the last check and begin e-filing. I'm not sure what to do.
