Homework is to be submitted according to a guideline that is nowhere to be found
If you don't need to submit anything for 3 weeks and it's so early in the term that you don't even know who your TA is, I would wait until you do.  You can't be the only one who has no idea what your TA wants if you don't even know who it is.

There's a pretty good chance you'll get a short orientation in your section where the expectations will be explained and you can ask questions.
