Testing IAP is going to require a test user that you create under iTunes connect. Plus code in you app to implement IAP. Then to test it you "purchase" the item from within the app, under the sandbox, using that user id.

As far as I know TestFlight is no different than testing the IAP on your device by building directly to your device.

I'm assuming that you didn't just add the IAP bundle id and expect it to do something.

If you have not added code to support IAP, that answer is non-trivial within the scope of a SE answer. Google IAP tutorial. There are lots of good ones out there.
