Is double tapping allowed on Square D Homline breakers? There are two slots under the screws. I’ve heard or read that if the manufacturer designs it fit that then it is ok

It will be embossed in the plastic on the side of the breaker body.
 
The instructions will tell you if it is OK or not. Most, but not all, small breakers it is OK.

(A) Terminals. Connection of conductors to terminal parts
shall ensure a thoroughly good connection without damaging
the conductors and shall be made by means of pressure
connectors (including set-screw type), solder lugs, or splices to
flexible leads. Connection by means of wire-binding screws or
studs and nuts that have upturned lugs or the equivalent shall
be permitted for 10 AWG or smaller conductors.
Terminals for more than one conductor and terminals used
to connect aluminum shall be so identified.
