"how come I haven't received it yet"
Does "it" refer to a Federal refund?
Did you print, sign, and mail your return paperwork? TurboTax does not mail it for you.
After 4 weeks from mailing, it should show up in this tool. How long has it been?

It takes 6 weeks or so to normally get a refund after filing on paper by mail. Longer if they have to review anything or extra processing. If it's been longer than 6 weeks, we can tell you how to phone a live agent at the IRS to inquire.
