While I could not further edit the Personal Property Taxes when I went back into my return and went to the "Update" on that item, (likely because I filled out the supporting details using "Forms"?). I just got a notification that I have maxed out the $10,000 federal deduction. However, I did go into another field that did not have any entries or Supporting Details and used the "edit>add supporting details" and that opened up the SD pop up window. I also confirmed the on other line items in my return were SD was used, I was able to double-click and open up the dialog box with the SD.
In prior years, when I had "Supporting Details" on my return, the next year, I was able to double-click in the box to get the SD from the prior year, absent the dollar figures. This also worked in other line items this year, but did not in the Personal Property Tax section. Hence, I used "Forms" to populate the data. When I used Forms, my line item entries from the prior year were all there, except for the dollar figures, as expected.
Not sure why it worked everywhere else except for the Personal Property Tax section, but, I managed to simply work around it.
