Apple Watch Siri can't find home; contacts show downtime contact instead of actually one.

There are some weird things happening with my Apple ID/contacts. I was asking Siri to route me home on my new apple watch and it said there wasn't one even though earlier I had in fact added a address for my contact but when I went onto my contact it had shown the downtime contact instead of my actual one. When I clicked the downtime contact to edit it, it went to my contact so I couldn't actually edit the downtime one even with the code.

And on my Mac when I click contacts it says that I have to of them the downtime contact which isn't mine shows up as mine with the one that is actually mine.

I would start by deleting your contact. Make sure the deletion syncs across all of your devices. I would recommend that, in the Watch app, go to General>Reset>Reset Sync Data. This often clears out contact syncing issues. Then, add your contact back and make sure it is selected as your info on all of your devices.

Set up your My Card in Contacts on Mac - Apple Support (AE)

If none of that helps, unpair and re-pair the watch.
