2017 mail in filing

So, this last tax year was the last year to file for my 2017 taxes, so I did. I know i got them in the mail on time, with a few weeks to spare. When can I expect word from the IRS? I still see nothing in my it's account for that year. I'd like to know if I'm getting a refund / owe the IRS. What can I do moving forward with this?
