FYI, I've come across other problems with WI Schedule SB, form 1, so heads up!! See below:
2/20/22: WI Schedule SB, form 1 NOT WORKING CORRECTLY. On one return, the LTCi premiums from Easy Step were carried into line 7 on WI Sch. B, BUT ALSO into line 6. That is, the "Additional medical insurance premiums" and SSA-1099 Medicare B premiums that were noted in the Easy Step section were NOT correctly imported into line 6, but replaced with the same number as line 7!! This alerted me to check another (alread-filed) return, no "Additional medical insurance premiums" were transferred to line 6. So, now I'll have to file a printed amended return :( And I'll have to review previous year's returns, too, in case this is a carryover glitch.
