Can anyone tell me why I received the state portion of my income tax return last month and have NOT received federal yet... Why is this, and I filed through turbo

TurboTax gets no information about the status of your refund.
In normal times, the IRS says that most filers get their refunds within 21 days from the time their tax return is accepted. Some refunds take longer.
Many returns are taking longer now since the IRS did not process returns for a while and there is now a big backlog of unprocessed returns. The IRS is currently not processing any mailed returns. 

Have you confirmed that your efiled return was submitted and accepted by the IRS?

Once your return has been accepted by the IRS, the IRS has full control over the refund process.

You can only track your refund at this IRS web portal.
