@jrhoya Indeed, Line S does not exist, and Line R appears to be misnamed in that tooltip.
I did not run into this issue as I'm using Worksheet 1, however I think it's safe to use Worksheet 3 Line Q and Line R in place of the requested Line R and Line S, at least given how the names line up with what we're asked to use on Worksheet 1.
The big caveat here is that I'm just a normal user and know nothing about taxes, so you'll have to convince yourself this is reasonable by reading the bolded names on the worksheets.
You might want to create your own issue as well, as my particular question was about TCJA rules (they save my kids a bunch of federal taxes, while increasing the state taxes very slightly).
