Estimates and Other Taxes Paid (in TT) - Other Income Taxes

Under "Personal - Deductions and Credits" - one of the topics is "Estimates and Other Taxes Paid".  Below that is "Other Income Taxes". The software shows last year's and this years numbers for comparison purposes. I want to find out more about the amount shown for this year. When I click on the topic, whether "visit all" or each topic, I am not taken to where these amounts are entered or shown in the software. Last year's is shown as about $24k, and this year's as about $17k. This is a significant difference and I do not understand it.  I thought/hoped  that clicking on "Update" would take me to where these numbers come from (or are generated from) but when I click, I am just taken to "Payments with Extension", "2018 Refund Applied to 2019", and "Other Income Taxes paid in 2019" - all of which are blank! No useful information at all.

 Where does the $17k/$24k I mentioned above come from, how can I find it in the software to make sure it is correct? I am concerned about the large difference I mentioned above, as my income is quite similar to last year's and the only major difference I can find in comparing last year's to this year's is this amount, and I cannot even figure out where this amount comes from. 
 
I hope this is clear. Unless there was a major change in the tax rate for my bracket, there is a $7k difference between this year and last year, in the mysterious "Other Income Taxes" and I need to try to find it to make sure it is correct, how it got there, etc. Thank you.
