Deductions & credits

Agreed ... it is unknown the timing of the debit however balance due returns have once again been put on the back burner so that returns with refunds can happen first so don't expect the IRS to debit the account anytime soon.  NOW  if you don't have the money for the debit when they do try to take it the debit will not happen so that may be what you need/want to do is to leave the account short and then make a correct payment directly online at the IRS site by 4/15 to avoid penalties.  https://www.irs.gov/payments
