Filing a 1099 will not effect the timing on your refund. The IRS releases most refunds within 21 calendar days after the e-file has been accepted (received), not 21 days from the e-filing date. For mailed returns, allow 5-6 weeks from the postmark date. (If you claimed an Earned Income Tax Credit and/or an Additional Child Tax Credit and filed before February 15, 2018, you’ll get your refund the week of February 27 at the earliest.)
