Did your parents already file their return and list you on their return?  

If they did, they will have to prepare an amended return to remove you from their return (amended return MUST be PRINTED and MAILED and can take 2-4 months to be processed..

They need to WAIT until they find out if their return has be REJECTED or ACCEPTED.
Then, it is BEST if they wait until they actually receive the refund (or payment due is taken from their account) based on their already filed return;  then they can start the amendment process

Above all  DO NOT DO ANYTHING until they find out if their return is rejected or accepted

For you, there is no chance that the amended return will get processed in time for you to e-file your return.

At this time you should simply PRINT and MAIL your return and not waste time this year to try to e-file

When mailing your return it is best to go to the Post Office and send it Certified with Return Receipt.
