2018 e file with deluxe package

I bought this package from turbo tax for $80 because it said I could e-file my taxes with it even thought the deadline for e-filing has passed. I'm here to figure out with my deluxe package how to do that, since the package stated even though the systems had closed that there was still a way to electronically file. My taxes must be filed immediately and I can't wait on the mail during this Covid-19/Coronavirus pandemic.
