Does TurboTax double-tax RSUs?

Not if you enter forms correctly. W-2 carries vest wages; 1099-B should reflect only post-vest gain after basis adjustment. Double-counting happens when $0 basis is accepted.

Where do I fix RSU cost basis in TurboTax?

In the investment income / stock sales section, when asked about basis reported on 1099-B. Look for options to indicate basis is incorrect or missing and enter vest FMV from your records. Exact wording varies by version.

Do I enter RSU vest income separately from W-2?

Usually no — it is already in W-2 Box 1. You adjust the sale's basis, not add vest income again.

What if I have dozens of RSU lots?

Use broker supplemental detail if TurboTax supports it, or enter lots manually with correct basis per vest date. The 1099-B adjustment helper on this site can compute per-lot adjustments.
