i-94? Can I file i-120, i-485, i-130 together? HELP!

A bit of a background...

I entered the US in May 2018 as a visitor. I'm a Canadian citizen and passport is from Canada. During this time my boyfriend and I decided to get married (Yay!). 

Now here is the part I'm confused about...

I came into that states via a Greyhound bus at the Detroit border. I talked to a CBP officer, he took my passport (presumably scanned it), asked me what I'm doing here, how long i plan on staying etc (at the time I had no intentions on getting married, so I said I was visiting for a few months). He gave me my passport back and directed me to the baggage check, I passed and got back on the bus. 

When I started to look up information regarding requirements for the forms i-130, i-485, i-864 I noticed it needed a copy of my i-94. After a bit of research I found the website where I can look it up seeing as I never received a paper copy . When I entered my information there appears to be no record of my i-94. It does however, show on another tool (history of arrivals and departures) that I gained entry on the correct date/place.

From what I read online i need to file i-102? Am I wrong?
I read some information that says I could get away with a affidavit from someone who knows I entered the United States legally, provide a copy of my Greyhound bus tickets and a print out of my history of arrivals and departures (also something about requesting information from the Freedom of Information Act?)

And if I do need to file this is it possible to file i-102, i-130, i-485 and i-864/i-864a all together? I noticed the addresses to send the i-102 is different then the addresses for the i-130, i-485 and i-864/a (those are all sent to Chicago).

Help...so confused!

So I decided due to being anxious and impatient to contact the "VJ Immigration Lawyers" advertised on this website. $38 later I have the answer I was looking for. I attached a screenshot of the response. I hope this helps anyone with similar situation/question!
