Yes, it would be best to amend your return to report the corrected 1099. TurboTax makes amending a return very quick and easy. You need to wait until the original return has been processed and until the 1040X amend form is available in mid to late March.
You could also wait for the IRS to send you a notice about the discrepancy in the 1099. That could end up involving penalties and interest for late payment.
