The issue is not how to start/file an amended return. It is that the 529 contributions are not shown on line 48 of 2020 MO-1040. The contributions were correctly entered during the Desktop interview process are not reflected in the MO-1040.
The same issue occurs on Line 49 of the 2021 MO-1040 form.
So my question is how should the MO tax credit be shown on the MO-1040. If it is not correctly shown, then I will need to file amended MO-1040s for 2020 and 2021.
