I am a foreign citizen who started an LLC in 50-50 partnership with a US citizen. I used to live in the US before and have an SSN. How do I file my taxes in the US?

I was under the impression that since our company is a pass through LLC, I would just file my regular federal and state taxes like I used to file when I lived in the US. I am not sure which state I should file the taxes in now. Also, we received a notice from IRS stating that we need to file Form 8804 and 8805 - when I read this up on the IRS website, it seems like IRS is asking the company to withhold 37% of my income in taxes.

You are going to file as a non-resident.  Since you don't live in the US anymore and you are not a citizen you can't file the same way that you did when you lived here.

TurboTax doesn't file non-resident returns.  For that we partner with Sprintax.  Here is a link.

The partnership is required to withhold taxes if it has a non-resident alien as a partner.  That is why the forms are required.  On the upside it means that your taxes will already be paid when you file the US return.
