i got the exact issue, here's the solution I found from older posts:
"The problem is TurboTaxes Billing Address Verifier. There here is the weird trick to get passed it. In theaddress field put in "gibberish" just let your fingers touch random keys Do the same for your city. YourState and Your Zip code should be correct. Put in your credit card info in and process the payment.Hope this helps."
So in the billing address window just enter random characters, but enter correctly for state and zip code.
I found this very absurd and ridiculous and I am starting to doubt turbotax product as a whole.
