Delete the extra state that is listed there by clicking the word "delete" next to the trash can

Click done

run the review again

Error is gone. 

I do not know how you are navigating there? because when I try to go back and fix the date, it does not give me the option to delete it, and I do not see those steps you are referring to

I ran into this issue as well and it turns out I had accidentally added a sales tax line item for a vehicle we purchased in 2020 twice.  I'm not sure how that happened but went back into Deductions and found the Sales Tax area & deleted the duplicate.  It then let me move forward and file.
