Why do I owe $ with negative 2022 income

[sfd2]

Hello

Prior to filling out form 6781 for capital loss I filled out my regular forms for an income of $2712 with a tax liability of $313.  I then filled out form 6781 which gave me a total income of Minus $288. WHY do I still owe the $313 from the $2712 income which is no longer valid with the $3000 max capital loss applied?? Net income now Minus $-288.  Please see the below:

You had a loss for your 2022 income

Your total income of $-288 comes from adding up the $2,217 in income from your businesses, your capital gain of $-3,000, the $495 of ordinary dividends.

Your Tax Breakdown 2022

Total Income	$-289
Deductions	- $14,857
Taxable Income	= $0
Blended Tax Rate	x 0.0%
Tax Liability  This is how much you were supposed to pay in taxes.	= $313

The $313 you owe comes from the $313 of total tax on your return.

Thanks

The tax may be from something besides income tax, like a penalty or self-employment tax. You can look on schedule 2 of your Form 1040 to see if you have any Additional Tax.
