My 2022 estimated tax calc of taxable income appears to be

[Tfes007]

In 2022 I prepared my 2023 estimated tax payments using TT.  My actual amounts in 2023 were almost exactly correct, however my calculated taxable income is $9800 higher than the estimate. It seems that the 2022 TT miscalculated my taxable income despite accurate inputs, resulting in an underpayment of 2023 taxes by over $2000.  I fear a penalty will be imposed, on what seems to be an error in the 2022 program.  Help!
