What's up with ordering IRS forms by mail?

I usually order some IRS forms by mail, including 1096, 198 and 1099-INT. But this year they seem to be unavailable on the IRS web site.

Does anyone know what's up with this? Is the IRS just running behind? If so, time is running out, since these forms must be submitted by February 28.

Or is it possible to submit these forms electronically with TurboTax? 

Thanks for any tips!
