Question regarding irc 121, form 1099-S

Just sold our home. We are asked to sign a form "Certification for no information" to see if 1099-S will be sent to the IRS. We bought our home for 5 years, lived as primary residence for 4 years, and rented one year prior to sale. We were expecting to utilize the 121 exclusions from capital gains tax, but this certification for no information form asks 7 questions, and one specifically asked if the property has ever been for "rental purposes", which it did. So will the title company generates 1099-S and we have to claim the 121 exception in next year's tax return?
