Hi Bill,
I humbly apologize, thank you for bringing that to my attention. I did not notice the heading that the first 6 worksheets were only for married and surviving spouse 😔. Sorry for ringing the alarms bells, just was a bit panicked because I waited until the last minute this year to file these taxes. Consider this closed. Still a bit weird though that the other calculation tools came out to around the figure I had calculated. Oh well
