The Long Term Care Insurance premiums are not being filled in on Wisconsin Returns, at least not for the 2021 tax year as of 2/20/2022.
My LTC premiums appear correctly on my TT 1040 schedule A Line 6 as entered, but this amount is NOT being carried over to TT WI SB Line 7. If I "zoom" from SB Line 7 to TT "Long Term Care Insurance Worksheet" for 2021, line 1on that worksheet is blank. If I right click on that to "Data Source" it points to a "Data Source" dialog that shows "LTC Insurance Worksheet Line 1, and indicates it is "From the federal return, Long Term Care insurance amounts.".
Of course, I can "Override" it - but my experience in the past is that so doing either generates errors or prevents electronic filing.
[Edit: This was MY ERROR. I incorrectly entered the LTC insurance premiums as LTC expenses. After fixing that - and clearing the override it was fine.
[Note that if you select a field and right click -> override it, that override "sticks" EVEN IF YOU DON'T CHANGE ANYTHING.]
