TTax tax calculation in 12% single bracket does not match IRS tables

[rpsontag]

I've  input all of the required data into  TTax, and the computed tax is less than the amount in the IRS 2020 tax tables on the same taxable income in the single filer 12% bracket.  Where do I look next?

IF you have any

1)   qualified dividends......... box 1b on a 1099-DIV

2)   ..Cap gain Mutual Fund distributions.........box 2a on a 1099-DIV

or

3)  Long Term gains from stocks or other securities sold during the year ...forms 1099-B/8949

Then those $$ are taxed at lower rates than in the tax tables, and special calculation worksheets are used.

Thank you very much!  It was a 1099-DIV that threw off my calculation, and with your advice,  I both learned something and was able to complete my check of the tax calculation!
