Alright ... TT doesn't set up payment plans and they are not ever just 2 payments. So it sounds like you may have owed for the fed & state and you set up a payment for each taxing authority. Proof of your payment will be in the account statement of the method you used to make the payment.
Log in and Scroll down and click on ADD A STATE to let you back in the return then go to the PRINT CENTER and save a PDF of the return WITH all the worksheets then review the filing instruction pages for each return for the method you choose to pay the balance due.
You can access your IRS tax account for your payment history and any scheduled or pending payments - https://www.irs.gov/payments/view-your-tax-account
