North Carolina state inability to e-file due to W-2 withholding more than 50%

I prepared to e-file my fed and NC state taxes, paid the $25 for the state, and then got a message to check my W-2. It was accurate. After several runarounds and loops, I finally got a message saying that if my state tax withholding was more than 50% of my pay, I could not e-file. But this message came AFTER several screens indicating that I could e-file. It felt like an add-on at the last minute. Clearly TT knew the percents of my W-2 at the beginning of the process, and a pop-up could have told me that if my state tax withholding was more than 50% of my pay, e-filing my state return wasn't possible. So you need to display this message earlier in the process. HOW DO I GET MY $25 BACK from TurboTax for this poorly designed software???? When I've called customer service for other issues, they are clueless, so a waste of my time.
