The car expenses back and forth to work are considered commuting and are not deductible.
The sales taxes you paid on a car you purchased may or may not benefit your.
You are allowed to deduct as an itemized deduction either, sales tax you paid or state income taxes you paid. Depending on where you live and if you have enough itemized deductions you may get no benefit from sales tax.
You can certainly add this to your TurboTax file and see if it makes a difference.
The only way to correct a
return that has already been filed is by filing an Amended Tax Return (Form 1040-X).
You should wait to get the
acknowledgement that your original efile is accepted.
If for some reason it
gets rejected you can correct the efile error, make any other
corrections and re-submit it.
If the original efile is
accepted you have to go through the Amended Return process, make any necessary
corrections, print it out and mail it in.
Unfortunately, the IRS will not
accept an amended return by efile.
The IRS website says that it
will take up to 16 weeks to process amended tax returns.
