What does TP state refund refer to?

what amount is required to be entered in the section ?

"TP state refund" means "taxpayer's state refund". 

A state refund is when a state refunds in the subsequent year some of the state income taxes paid in a prior year.
 

Here are some other places you might find the amount of last year’s state/local refund to report on your current tax return:

• Last year's state tax return
• Your bank statement showing your entire state/locality refund
• Your state tax agency (for state refunds) or municipality (for local refunds)

If you transferred last year’s tax data to this year's return, your state and local refunds are automatically brought over with your other tax info.

Alternatively, your state/locality may have sent you a 1099-G form (if they haven’t gone paperless). You should receive your 1099-G by mid-February if your state/locality still sends out paper forms. If you did get a 1099-G, make sure it's for a state/local tax refund, not unemployment compensation.

If you get a Form 1099-G, this how you would enter it:

Where do I enter a 1099-G for a state or local tax refund?

Important: If your 1099-G shows an amount in box 1, go here for alternate instructions, as the steps below won't work.

Otherwise, if your 1099-G has amounts in box 2, follow these instructions:

For TurboTax Online

1. Open or continue your return in TurboTax.
2. Go to Federal, then Wages & Income, then Other Common Income.
3. Select Start or Revisit next to Refunds Received for State/Local Tax Returns.
4. Answer a few more questions about your refund until you get to the Tell us about your refund screen.
5. Enter your total refund received in 2023.
   • Enter the amount in box 2 (state or local income tax refunds, credits, or offsets).
   • If you received multiple 1099-Gs for the same state or locality, both with the same tax year in box 3, enter the box 2 sum.
   • For example, you received two 1099-Gs from Colorado. They both have 2023 in box 3, and their box 2 amounts are $1,000 and $800 respectively. You'd enter $1,800 in Total refund received in 2023.
6. Enter your total of all your payments and withholding.
   • Enter the total taxes you paid to the state or locality for the same tax year as the refund (this includes withholdings as well as estimated tax and other payments).
   • You can get this amount from your state or local tax return for the tax year of the refund. Look for a line near the bottom, often bolded, that includes the phrase total payments.
7. Enter tax year of refund, which is box 3 of your 1099-G.
