After you file

Correct, the only reason I amended my return was to correct the "overpayment" error, nothing else was changed.  I did complete the amended return on turbotax with the correction of removing the erroneous estimated tax, but have not sent it yet.  Sounds like I should not send it, pay the IRS the $300, and turn off the amend flag?  Since I did complete the amended return will this affect next year's TT return?  Thank you so much for your help!!
