Thank you! I found a brief estimated tax summary that I thought would transfer figures over to the vouchers, but, no, I still had to manually input line by line to create the vouchers. Then I found a 'what if' worksheet which goes into more detail for estimated taxes for future years, which I went through. Frustratingly, I can't make the two tools line up as far as the estimated 2022 tax, nor does the information link to the vouchers in any way that I can find. Gotta love technology. 😉
