Thank you Andrea46. That is the correct answer. If you don't use TurboTax to file your state return, apparently TT doesn't give you access to print all the various forms available. After adding the state return (but not actually completing it) I then had access to the federal forms showing the TT and government worksheets (as someone mentioned under Section V of the federal information worksheet) and could verify that in fact I had scheduled my payment to the IRS on 4/15/24.
