The following diagnostic is generating:

Due to a carryback the full amount of overpayment is not being brought forward to the next quarter. For Maine e-file purposes Maine will only allow the full overpayment to be brought forward. Either suppress the penalty or paper file this return.

Solution:

This diagnostic applies when a carryback causes an overpayment not to be fully applied to the next estimated tax quarter. However, Maine e-file requirements mandate that 100% of the overpayment must be carried forward.

Option 1: Suppress the penalty calculation (if applicable), allowing the full overpayment to carry forward.

Option 2: Paper file the return instead of e-filing.
