Hello, I believe I have already paid for 2018 versions of turbo tax, can you please confirm where I can find them? Did I use the on-line or download version last year?

When you sign in to your Turbo Tax account, to the left you will see Previous Taxes. Click that to see if your 2017 is listed. If not, then you may have used the download.   If you paid for the CD/Download, it will be saved in your account. You can access your download from any computer.
