After you file

I noticed that on last years return (2021)

 

I went back about 5 years of HR Block returns and discovered while taking the $3k deduction, they were not reducing the capital loss carryover.

 

This error is so fundamental it makes one wonder what else they've gotten wrong.

 

I hate TurboTax but it looks like I'll have to go back to them.  (TT was terrible handling short sales and completely failed to deal with wash sales.  But that was years ago - but then, that was why I left TT.)
