I've used TT for years, but this is the first time a state refund has been adjusted. In TT 2020, on first page of state return, the expected return shows $115, which is the amount the state lowered the refund to. However, after making no changes, when I click Continue, the refund immediately recalculates to $571, which is what I submitted.

Is this a program calculation error? If this is a data entry error, where do I look to troubleshoot this? After I reviewed the data, both W-2's and charitables are entered correctly.

The difference in AGI is the amount of the charitables.
