How can I indicate on my state return that I paid the tax due already on my state's tax portal?

I'm ready to file and have a tax due on my state (Illinois) return.  Have not had any state tax due on prior years.

I went on the state tax portal (mytax.illinois.gov) and paid the tax due identifying it as an IL-1040 payment.  That's not an (ES) estimated payment.

I don't see a way to indicate that I paid the tax in TT.  I only see where to enter Estimated Tax payments.

Should I enter the IL-1040 tax I paid as an Estimated Payment, (and the return would show no tax due) or if the return shows the tax due, does the software give me a different way to indicate the tax has already been paid when filing?  I do have a confirmation code for the state tax payment.

Thank you.
