Read the filing instructions that print out with your pdf----what does it say there about how you will pay your IN state tax due? TurboTax does not "pay" your state tax for you. TurboTax only passes the information for debit or credit to the IRS or state for you and then it is up to the IRS or state to take the payment from your account. Some states do not want/allow direct debit for the tax you owe---and want either a check or money order or payment directly on the state's own tax web site.
I seem to recall from prior years, that Indiana was one of several states that doesn't allow you arrange a Direct Debit from a checking acct at the time you e-file, and you always had to pay them separately. Of course, they can change that in a future year, so you always have to check your printed State Electronic Filing Instructions sheet carefully to see how it is going to be paid.
NC didn't start allowing that until 2 or 3 years ago. IF Indiana allows it, your printed State Electronic Filing Instructions would look similar to the following.....with your Routing and Account numbers showing:
Indiana does not allow your taxes to be paid directly from the tax return. Please see this website to pay your Indiana tax due: DOR: DORpay - Tax & Bill Payment - IN.gov
See the instructions for Line 26 on page 11 of the 2020 Indiana tax instruction booklet:
