A multi member LLC is taxed as a Partnership and the Partnership must file it's own return form 1065 BEFORE the members can file their own person returns since the each need the K-1 issued to them by the partnership. The form 1065 is due 3/15 so if you have not yet filed the 2018 return it is now very late ... even if you put it on extension is was due 9/15 so it is still late.
If this is something new to you the I HIGHLY recommend you seek local professional assistance to get your books set up properly and get educated on how to complete the first return... after that if you fee comfortable with the 1065 then you can use the TT Business version to complete the partnership return.
And the partnership deducts the rent paid for the business location on the form 1065 .... or are you referring to you each having your own OFFICE IN HOME expenses ?
