Merging functionality for duplicate mod items

Okay, I made a modpack that includes both Croptopia and Bewitchment. I've noticed that both of these mods create garlic as an item/crop. What I'm looking to do is allow them to be used interchangeably in recipes. I was advised the simplest way would be to create a tag encompassing all of the items, then create/edit recipes to utilize the tag.
After doing some digging, I did find that the .jar for Craftopia already utilizes a "garlic" tag, so I copied it over to a new datapack and inserted Bewitchment's garlic. I then copied over bewitchment's recipes, and substituted garlic the item for garlic the tag.
But, it would appear I've goofed somewhere in here. This is where I'm at right now.
