Quick troubleshooting steps

1. Refresh the source URL – Open the link in a browser. If you see a “Page Not Found” message, the endpoint is dead.
2. Check the platform’s developer portal – Most gig platforms publish updated API documentation. Look for a new “/v2/earnings” path.
3. Regenerate authentication tokens – In your tax app’s settings, re‑authorize the connection. Tokens typically expire after 30‑90 days.
4. Download the file manually – Export your 1099‑K or 1099‑MISC from the gig platform’s dashboard as a CSV or PDF and upload it directly into your tax software.
5. Verify with a secondary tool – Use a free quarterly tax payment calculator 2026 (e.g., the IRS Self‑Employment Tax Calculator) to cross‑check totals.
