I put information in if I was in a common-law relationship but I'm not but despite setting it back to Single it won't let me file as TurboTax still has that information somehow?

"Your marital status cannot be single if you've entered information about your spouse/partner. Ensure that you've entered your marital status correctly, noting that if you..." is the Netfile Error.

So how do I somehow clear that information that I don't have access to?

Do I need to start over? Pay again to start a new return?
