In that screen, click the "State Refund Wksht" and input the amount in the first line as an override (assuming you are sure it is taxable.) 

If unsure, enter all the information in the Refunds Taxable in 2020 Worksheet. Do NOT enter as indicated in the opening sentence here. 

Thank you for your response. However, I am still having a hard time figuring out where in the software I have to input the amount. Could you show me by a captured photo?

Thank you so much for your help!!

My problem was resolved. Now, I see the amounts(the state tax refund) on the tax return.
