Yes, if your 2019 return has not processed, you need to enter 0 as your AGI for your 2020 tax return to process. Hard to say why you refund is taking longer. There are many issues that can delay refunds, including ones over which the IRS has no control. Here are the top three categories:
Administrative requirements
- Earned income tax credit or additional child tax credit - If you filed in February or earlier and claimed either of these credits, the 2017 PATH Act requires processing to be delayed. The IRS just recently started releasing these refunds
- Refund Offset - The IRS may have discovered you have delinquent debts, which they're legally required to deduct from your refund. You'll receive a notice about the offset.
Missing, inconsistent, or suspect information
- The IRS found errors, inconsistencies, or missing info on the return. For example, you and a former spouse both claimed the same child as a dependent.
- The return is under review, which can happen randomly.
- The IRS suspects identity theft or fraud.
Delivery glitches
- Your refund check could just be delayed in the mail. The reason could be as simple as a new postal carrier learning your route.
- Electronic payments may be delayed by bank transfer and posting issues.
