Federal Carryover Worksheet Error

Thank you for your quick response. I have desktop version and had previously tried everything you suggested (deleted, save, close, restart). After several hours of frustration, I was just about ready to print the return and mail it in, but then I just kept hitting the "transmit" button over and over again ignoring the error. Finally, to my surprise, after about the 10th try, the file said "transmitted"!. I also received email confirmation that IRS received E-file. 

I found mine in local not state - got this help from grok & was finally able to file.

**This is a common TurboTax glitch (especially for 2025 returns) that blocks e-filing even though the Federal Carryover Worksheet itself isn't submitted to the IRS.** It usually stems from a stray "0" entry, prior-year import issues, state estimated tax data, or a locked field in the worksheet (often related to capital loss carryovers, NOLs, Section 179, or similar). It rarely happens in H&R Block, TaxAct, or TaxSlayer.

**Quick tip before trying fixes:** Back up your return file first (File > Save As in desktop version, or download a copy if online). Try these steps in order—they resolve it for most users.
### 1. Check for and delete a stray "0" (fastest fix, works for many)
- Switch to **Forms mode** (top right in desktop; or use the search bar).
- Open the **Federal Carryover Worksheet** (it may say 2025 at the top).
- Look below the main table or in the body of the form for a lone "0" (or any blank field demanding a State/Local ID).
- Delete the zero (leave the field completely blank).
- Go back to the main screen, run **Review** or **Check for Errors**, then try to e-file.
### 2. Fix erroneous state estimated tax entries (very common cause)
- Go to **Federal Taxes** (or **Personal > Income & Expenses**) > **Deductions & Credits**.
- Scroll to **Estimates and Other Taxes Paid** > click **Start** or **Revisit** next to **State Estimated Taxes for 2025**.
- Find any entry showing $0 for "2024 state estimated taxes paid in 2025" (if you paid none).
- Delete the zero or edit the payment details (correct the date if a Q4 2025 payment was entered wrong, or move any Jan2026 payment out if it doesn't belong).
- Save, run Review, and try e-filing again.
### 3. Clear and regenerate the worksheet
- In **Forms mode**, open the **Federal Carryover Worksheet**.
- Delete the entire worksheet (or clear all fields if deletion isn't allowed).
- Save your return, close TurboTax completely.
- Check for updates (Help > Check for Updates).
- Reopen, let it re-import/recalculate carryover data from your prior-year return.
- Review the worksheet and re-
enter any carryover amounts manually if needed (pull them from your 2024 Schedule D or Form 1040).
### 4. Additional troubleshooting (if still stuck)
- **State/Local ID field issue**: In Forms mode on the worksheet, enter your two-letter state abbreviation in the State/Local ID field (even if you have no state income tax). Also fill in Column D with any actual state tax withheld from your 2024 return if it's blank/
- Update TurboTax fully and restart your computer/browser.
- Try e-filing repeatedly (some users clicked "Transmit" 10+ times until it went through).
- Switch browsers/devices or clear cache/cookies (for online version).

After fixing, run **Review** again—the error should clear and let you e-file.

**If none of these work**:
- Contact TurboTax support directly through the Help menu (chat or phone—mention "Federal Carryover Worksheet error" and reference the community thread for faster help).
- Or switch to paper filing as a last resort (download Form 1040, fill manually or via software print option, mail it—postmark by April 15, 2026, to avoid penalties).
- A tax pro or CPA can usually override/fix this quickly if you're short on time.
This should get you filed—it's almost always a software glitch, not an actual tax error.
