I put in all the information correctly from the 1099-G state unemployement form, but turbotax keeps looping me back to that form with the word Review in red. Why?

There is something the program does not like. Review the entries. Is there a decimal moved?  There should be a place highlighted with the error. You may have to scroll around to find it. 

 You can fill this form out for someone to call you and share your screen to help you find the issue.
