I am having the same problem as many on line 12b review and the Cares Act cash deduction. The solution is to delete charitable donations since I am taking the standard deduction. However, I CANNOT do that as the Minnesota return allows me to deduct this.

Of course you can wait for an update, but the following seems to work if you want to file before that. 

Please return to the Deductions & Credits section, scroll down to "Charitable Donations" and DELETE any cash entries you made there. 

(NOTE: Some states allow you to Itemize Deductions when taking the Standard Deduction on the Federal Return. To include cash charitable donations as an Itemized Deduction on your STATE return, you can enter the donations as "Items" select "I'll value them, select "Other intangible property" enter the description as CASH, since it was and the amount as the value.)

Go back through the review. The program will ask you for your charity donation again although it may not be until after the state return is finished, at the END of the FINAL REVIEW.  (After the "Tax Summary for 2021" screen)

 Enter the amount up to 600 Married Filing Joint.

Unless your cash donations are limited by your income, this procedure (listing cash as items) will give you the same result on your state return as entering under cash donations. 

The Tax law allows a Taxpayer to claim Charity Donations on their Schedule A or, if using the Standard Deduction, on their 1040 line 12b as an addition to their Standard Deduction amount. 

This amount can be up to 600 for Married Filing Joint, or 300 for all others.
