Haven't got my tax return, I e filed over a month ago, it's been approved but i haven't heard anything.

According to IRS, to receive a refund, it should take around 21 days after the e-file has been accepted. (not from the e-filing date). To check refund status, please go to TurboTax Refund Tracker and https://www.irs.gov/refunds.  If it has taken longer than that, you might want to contact IRS.  However, please review the first article below before you call IRS Telephone Assistance for Individuals: 1-800-829-1040
