Those are the only possibilities other than your Congressman's local office, if you wish.
However, are you sure your IRS Taxpayer Advocate Service office is closed? They are closed for walk-ins, but they are still taking phone calls in most states. They are busy, so you may have to ask for a call back.
At the following IRS website, find the USA map and click on your state, and it will give you the number of your area's IRS Taxpayer Advocate.

If you efiled, you should double-check to be sure the return was efiled successfully and accepted.
If you used Online TurboTax, you can sign into your Online Account and check the efile status at the Tax Home.
If that showed it was accepted, you can use the "Where's My Refund" tool at the IRS website below to monitor the status of your Federal refund.

NOTE: When using that tool, use only the Federal refund amount, and not any total refund amount that includes a state refund.
The amount to use is on your Federal Form 1040, Line 21a.
