I have a Itemized Deduction of 6570. I have no idea where that's calculated from. I don't have anything listed under the most common itemized deductions other than State and Local taxes so I'm not sure how it went up that high. If it's due to my Capital Loss Carryover, couldn't that be used with a Standard Deduction instead and overall reduce my taxes further?
A capital loss is not part of the itemized deductions. Capital losses appear on Schedule D and then are carried to the front page of your 1040, line 13. Capital losses in excess of capital gains are limited to $3,000. If you have a negative amount on line 13 of you 1040, you received benefit for your capital loss carryover. Amounts not used this year are carried to next year.
Your standard deduction is $6,300 if you are single, $9,300 for head of household and $12,600 if you are married filing jointly. If your deductions are above the relevant standard deduction for your filing status a Schedule A will be generated and you can see the itemized expenses. If your expenses are below these amounts you will not have a Schedule A. You will be able to deduct either the standard deduction or the amount on Schedule A. The reason the $6570 is higher than you expected could be applicable deduction for sales taxes.
