Did the letter come from the state or the IRS? Remember they are completely different agencies with different rules. Also, when you talk about your expected refund, remember that the state and federal refunds are completely separate, they don't come together and one might be paid while the other is reduced or delayed. Only the agency that sent the letter can explain why they sent it.
If this is an IRS letter, you can contact the taxpayer advocate service, they should help explain things for you.

If this is a state letter, you will have to keep working with the state.
You may also need to hire a tax professional to help you understand your situation, if you have issues that cover many years (the stimulus was only in 2020 and 2021).
If you are low income, you can contact the VITA program to have a trained volunteer help you.
