The IRS page is incorrect. It has had constant crashing due to the large amount of web traffic.
I spoke with someone from turbotax today.
And clarified, because I had the same issue and went through exactly what you're going through
You will get your stimulus on your turbo card.
I'm having issues accessing mine and I'm sure you could use the money but we have to be patient.
***EDIT*** it seems the IRS website is fixed as of now. I would try to enter your info as soon as possible
