So it found your information OK previously? That IRS WMR tool can be squirrelly at times, and your return can move in and out of various stages when it can't be found. Just keep trying it each day.
Be sure you are entering the correct Federal refund amount. The figure to use is on your Federal Form 1040, Line 21a. Do not use any total refund figure that TurboTax provides, which could be the sum/net of your Federal and state refunds (if applicable).
You can also try phoning the IRS refund hotline. I've seen it work for some users before when the WMR tool didn't.
