TurboTax flags W-2s as duplicates if the Employer Identification Number (EIN), employer name, and most details are identical, even if you have multiple W-2s for different amounts, such as lottery winnings from the same employer.
To handle this:
1. Combine the amounts from all three W-2s into a single W-2 entry with the same employer name and EIN.
2. Enter the total wages ($3,000) and any other amounts as one entry.
3. Keep the original W-2 forms for your records, but enter only one in TurboTax.
This approach avoids duplicate entry errors, as TurboTax expects one W-2 per employer unless the EIN or employer name differs.
