If going with standard deduction, do you go back and delete itemized deductions to remove potential burden of proof in case you lose your receipts?

If you're taking the standard deduction, there's no need to go back and delete your itemized deductions, because the Schedule A will not be filed as part of the tax return.  So those entries go nowhere.

I realized I didn't pay for my mother's car registration so now it won't let me file my taxes without that section filled out or I'll have to pay $80 in order to file my taxes because it's saying that I itemized my taxes with the car registration. I can't delete it, so how do I removed the itemized deductions completely so I can file standard? @ThomasM

Even if you are taking the standard deduction on your federal return, it's a good idea to leave your itemized deductions in your return because they may be deductible on your state return.

 

To delete the entry for car registration fees, please follow these steps:

1. On the Deductions & Credits screen, under Cars and Other Things You Own, click the Revisit box next to Car Registration Fees.
2. On the screen, Enter your car registration fees, click the delete (trash can) icon next to the entry.
3. Click Continue.

 

You can also delete the entire Schedule A to remove your all your entries for itemized deductions.  If yoiu do this, they will not flow to your state return.  Please follow these instructions:
