I'm here to share details regarding 1099 in QuickBooks Online.
If you e-file your 1099s with us, it will be postmarked on January 31st, and a printed copy will be emailed/mailed to your contractor to the email addresses from your contractors' profile. To avoid issues, ensure that the email address is accurate and active.
Also, the delivery time may vary depending on the United States Postal Service (USPS) and the contractor's address. There may be possibilities that some contractors may not receive the forms on time due to delivery delays or other unforeseen factors.
