To check your e-file status, sign in to TurboTax, and go to Tax Home (if you're not already there). If you've submitted your return, you'll see a pending, rejected, or accepted status. If you haven't submitted your return yet, you'll see Let's keep working on your taxes! and sections like Personal Info and Income & Expenses.
Your e-file status is different from your refund status. If you want to track your refund, go to Where's My Refund.
Did you receive an email that the return was accepted by IRS? (check junk drawer too)
