Deductions & credits

My wife and I sold our main home in 2019 which we lived in since the late 90's, and never rented. No 1099-S was completed or sent in to IRS. Gains from the sale were less than the $250,000 of that gain from your income. You may qualify to exclude up to $500,000 of that gain if you file a joint return with your spouse. Question is, with several conflicting answers is, do we need to report this on our tax reporting? Or, can it go unreported based on the above.  Many thanks  BTW - we purchased our current main home in the same county and state. What sayeth the IRS on this?   Thanks
