Ok... So... Looks like I figured out the issue.. and things are all correct on the TT side...
So.. 1040 Line 25c is from the "Tax Payments" worksheet...
In my case, the 8959 line 21 was very close to the "Tax Payments" worksheet amount and hence the confusion.
it might help that TT can update the 1040/1040SR worksheet to direct to the "Tax Payments" worksheet when one double clicks on the form entry.. this will avoid the confusion that I had.
