Dissolving LLC - Interest Holder vs. Owner

What is the name of your state? Chicago, IL
2 years ago I began a small tech startup as an LLC with 2 other individuals. Per my agreement, I received a regular salary and a 5% share of the business.

For various reasons, the business is now dissolving. I was told (by 2 others) that my interest in the company was generally nullified because I was classified as a 5% "interest holder" not a 5% "owner".

Digging deeper, I learned that my name is not documented as a member of the LLC anywhere. I trusted the other 2 (my mistake). However, I have been paying Fed/State taxes as an owner each quarter.

3 questions:
Can the other 2 simply take away my 5%?
Should the amount in taxes I paid have been relative to my degree of ownership (5%)?
Should I have been paying taxes as an owner at all given my undocumented "interest holder" status?

Thanks

whoever registered the company owns it...

were you all listed as owners?

I own an LLC company and I am the only one listed as owner.

If your name isnt listed anywhere as anything than you'll have a hard time proving your even involved.

Legally I don't think you are even involved.

how about?

I am not a lawyer, but if i found out i was not legally responsible for business or losses and debt, i would walk away and amend my income taxes.
