Lacerte was incorrectly calculating the child care credit on State of Oklahoma.  They were only calculating the credit based on the refundable credit from federal and not taking into effect the advance payments.  The update changed all the previously filed returns to the correct amount.  I am sure that I will have multiple returns that need amended.  Do any of you know how to create a filter to check for previous returns that may need to be amended?  I have already filed over 250 returns and do not want to have to review each return to see if it has changed.  Thanks for your help!
