After filing in 2021 irs says it’s still under review

TurboTax gets no information from the IRS after you file your tax return.   You can call the IRS to see what is going on.

Call the IRS: 1-800-829-1040 hours 7 AM - 7 PM local time Monday-Friday
When calling the IRS do NOT choose the first option re: "Refund", or it will send you to an automated phone line.
So after first choosing your language, then do NOT choose Option 1 (refund info). Choose option 2 for "personal income tax" instead

Then press 1 for "form, tax history, or payment".
Then press 3 "for all other questions."
Then press 2 "for all other questions."
- When it asks you to enter your SSN or EIN to access your account information, don't enter anything.
- After it asks twice, you will get another menu.

Press 2 for personal or individual tax questions.
Then press 3 for all other inquiries
It should then transfer you to an agent.

IRS Tax Topic 151 is a notification from the Internal Revenue Service (IRS) that affects the status of your tax refund when you have outstanding government debts. It indicates that the IRS intends to use part or all of your refund to offset your debts, such as unpaid federal taxes, child support, or federal student loans in default.
