You need to 'catch up' on the depreciation by means of Form 3115.
However, this is a confusing form and TurboTax does not support it. I highly recommend going to a tax professional (preferably one who has experience with Form 3115) to have them do your tax return this year.

When you talk to the tax professional, the proper terminology is that you should have "depreciated" about $96,000 by now, and "depreciation"
lowers your basis. Recapture (for real estate, it technically is "Unrecaptured Section 1250 Gain") happens when you sell the property and you owe tax based on the depreciation that you took.
