George is correct, credits are tracked by the SSN/EIN.  They are not used, however, until you either print the return or efile the return though.  So, if you have not printed or efiled the return, your credit has not been used.  You can have as many copies of a return as you want in the system.  The credit does not use until you take one of those two actions.  However, if you find that you need a refund you would need to submit a refund request here: https://accounts.intuit.com/app/oirr.
