was line 11 of the 2021 1040 a loss? then you had a net operating loss (Turbotax does not compute this). you can use schedule A of form 1045 to figure. https://www.irs.gov/pub/irs-pdf/f1045.pdf that gets entered on schedule 1 line 8.
was any of the loss limited to the passive loss rules form 8582, Turbotax carries that forward automatically.
