It has not been six months since February--since June is the sixth month of the year--at most it might be five months---which is a long time. You got a letter asking you to verify your identity. Once you provide the information the IRS needs it usually takes about nine weeks. But....the IRS sent the humans who do those reviews home for about two months, so the clock stopped ticking on the time it takes to do the processing of a return like yours. They are back now, so watch the IRS refund site for any information. TurboTax does not get any updates after you file, so there will not be any news on this site about your refund.
