On turbo tax it says I'm.due a refund of $1,950 but it says I have to mail it to you IRS I was wondering if I could file it through my phone instead to make it faster

If the program is stating that your return needs to be mailed, it is usually due to certain forms within the return that are not supported for e-file. If that is not the reason in your specific case, you may try switching from mail to e-file.
