Hi Pilot2023. Welcome to the site!! You should have two u-bolts on your transom.
There is one on each side and are most likely below the swim platform. You need a towing harness

The spring clips connect to the u-bolts, the tow line itself will connect to the piece in the center of the harness. There are a wide variety of tow lines and towing harnesses to choose from.
Take a look at the following retailers:

www.westmarine.com
www.overtons.com
Overtons seems to have the largest selection of skiing and towing merchandise out there. That is probably where I would start looking.
Best of luck. Remember to have a dedicated spotter, even if one is not required in your state (though they are in most).
