What is the information for the "Total of all your payments and withholding?"

Hello, need a bit help as I have not touched Turbotax for a while.

 

As I am inputting the refund information (1099-G) to the "State and Locality" section, there is a box asking "Total of all your payments and withholding." Which line does it refer to in my 2019 tax return forms?  

 

I tried to check the Q&A in this forum but not quite getting the answer I want to know about.

 

I used "Itemized Deduction" for filing 2019 return in 2020 as I had donation records and also mortgage payments. The 1099-G I received from state government only has the refund amount on it, no other information.

 

I checked the listed information under HELP, but I am still not quite understanding what exact information do I need add up and put into this box......can any one help me figure it out??
