Hello, and welcome!
It sounds like this is your 'return' trip, so you've already shown your photo ID when you traveled from NY to Hartford (unless that was a completely different trip you made in the past) and that's in your favor. In addition, if you have a TSA Precheck number, you've been 'background' checked in the system, so even if you have no other forms of ID with your photo on them, they can check your identity through public databases available to the security screeners.
Even if you have no photo ID's with you, having anything else with your name and address might help. This is TSA's list of acceptable ID's:
Even if you have none of these, you should be okay to fly after they screen you. The additional screening will obviously take longer than usual, due to your circumstances, so, leave extra time to get to the airport early--2 hrs. early) and tell them as soon as you check in, that you lost your driver's license and that was your only source of photo ID.
I wish you much good luck and a wonderful flight!
