Final review being stuck in a loop has been happening when a 1099NEC has been entered in the program.  It happened last year too with the 1099MISC, they fixed it at some point.

You can either rely on your own expertise as to whether the return is correct and skip teh review.

Delete the 1099NEC and enter the income directly on Sch C

Wait for an update to fix it.

If you dont have a 1099NEC entered then youve got  a new problem that I havent seen yet.
