I didn't list all my deductions on the federal return because I knew the standard deduction was more. This info was used to do my state tax incorrectly.
Unfortunately No, Once your State has your Tax Return You can Not get it back there is nothing you can do "Unless" it is Rejected. If it is Rejected make needed corrections and add what you forgot and Submit it again.
If it is accepted, you will need to prepare an amended state return and your amended return Must be Mailed It can Not be E-Filed.
Pending means Your State has received your return, but just Has Not reviewed it yet. It will remain in "pending" status until it's either been Accepted or Rejected by the state agency.
