I need to find out if the lien I sent was done correctly and will stand up in court?

I recieved paperwork from the homeowners lawfirm and Levelset is included in the lawsuit. I rent out telehandlers for construction projects. July 2022 I rented a telehandler to a subcontractor who was doing a job in Wyoming, on a residents house. The homeowner was footing the bill for the rental. The homeowner ended up paying for Transportation from Idaho to Wyoming and three days rental. The telehandler was needed an extra day and transportation back to Idaho. The homeowner told the subcontractor he was not paying for that. In short, the subcontractor, nor the homeowner have paid me. I sent an intent to lien to the homeowner, since my equipment was used on his project, and then sent a lien to the homeowner. The intent to lien never made it to the homeowner, but he has received the lien. I now have papers from his lawyer stating, the lien needs to be removed because the homeowner never received an intent to lien. Also, I am over my 120 day window to lien because I am a materialsman, so 120 days is all I get to send a lien. When talking to a representative of Levelset, I was told that an intent to lien does not need to be sent. Then, just today, talking with another representative of level set, I am told there is another form that should have been sent prior to the intent to lien. I need to figure out where I stand legally? Do I drop the lien and go about getting my money another route? Or keep the lien in place?
