I am having this same exact problem, and its looking like turbo tax is attempting to qualify my CA state unemployment benefits as taxable income, which is should not be doing as CA does not tax unemployment benefits, as far as I understand it. I went and put all my taxes in the same way in H&R Block online and I dont owe as much in my HR Block state tax return as I do in my turbo tax state return... so Im thinking that turbo tax may have an issue going on? Im just speculating...but I 100% know for sure that I never added my unemployment benefits into my state return a second time or made any mistakes in this regard. I dont want to pay more to hire a turbo tax professional just to confirm that there is an issue with the turbo tax software after the American Rescue Plan act changes were made. (My turbo tax state refund amount suddenly changed since the last time I logged into my state return one week ago and I havent made any changes on my end). I REALLY wish that turbo tax online offered a "change history log" of all changes to my return step by step with the date and time and what form or numbers were altered with each entry that I made or that turbo tax updated, so that I could confidently identify the exact changes whenever I see something suspicious change or help me to identify potential mistakes that I made or that turbo tax possibly made... (this is a feature request Turbo Tax, please and thanks).
