I have owned my house for 2 years prior to selling my house, however the system is not acknowledging that I have.

The date purchased and the data sold must be greater than 730 days.

There may be a check box or entry that was missed.  If not, a diagnostic file is an option, see below the entry instructions.

• Search (upper right magnifier) > Type sale of home > Enter > Use the Jump to... link
• Select 'Yes' it is the sale of your main home
• Select 'Continue' on Sold A Home page > Enter the address of the home
• Answer the question about whether you receive a Form l1099-S > Date Sold, Selling Price and Selling Expenses > Continue
• Next, enter the 'Date Bought or Acquired' (This tells TurboTax how long you owned it)
• Enter your cost
• Answer the question about how many months you lived in your home (must be at least 24 months)
• Continue to answer the questions to arrive at your exclusion

The house must have been your primary residence for at least 730 days of the last 1526 days you owned it. The closing date of your sale does not count as a day having lived in the property. If you moved out say, 1 week before the closing date, then it's perfectly possible the property was not your primary residence for the full 730 days.
Rarely does someone vacate their residence just one day prior to closing on the sale. I've only seen that when there's a lease back agreement as part of the sales contract. But even then, the day count stops one day before the closing date, because as of that date the owner no longer owns the property.
