Your post indicates that you're using TurboTax Online? Is this the case? The reason I ask is because I've seen other users using the Desktop (CD/Download) having a similar problem.
Downloaded to desktop. Using file at this location. Turbo Tax in a loop when inputting direct deposit bank routing info. Does not recognize these numbers.
@coolbreeze50 I'll report your issue to TurboTax Moderators for further investigation. As I said, you're not the first to report this issue.
A Moderator may reach out to you by email. Please make sure your email address in your TurboTax account is current.
@coolbreeze50 I had another Desktop user who was able to enter banking info into the SC program ONLY IF they entered the banking info into the federal program. You may want to try that, if you haven't already.
It would be best to contact us by phone so we can look into this issue further. Please follow the instructions here to contact us by phone @coolbreeze50.
Please advise when South Carolina will accept TurboTax e-file results.
