I have the same question!!!!! Married, joint. These are all approximates: Last year we had taxable income of $15700. We paid $2500 in Taxes. This year, 2023, on Line 15, in the final review shows taxable income of $40000. And our taxes due are $700 Federal (and state is $1500 which makes sense). Huh? Now... the difference is the majority of the additional income this year is the sale of stock. I kept the sale within the 0 range. So, is the reason I'm seeing this low federal amount due because even though the total Line 15 shows the stock sales, even though this amount shows the capital gains they are backed out since they were within the 0 threshold? And the program just ignores this line item? Line 7 shows the capital gains and I will be attaching Schedule D as required (it states "if" required but I assume it is as the box is unchecked).
