Incorrect 1098-T Box 5 - File for extension?

I received a 1098-T form from college and they mistakenly put my pre-paid (529 plan) amount into Box 5 (Scholarships and Grants).  They admitted their mistake and said they will send out a corrected form, BUT they can't get the forms as they aren't available from the government at the moment.

Can I still file my taxes as $0 in Box 5?  Or will doing this totally conflict with what the college has sent to the IRS?  I definitely need to use the amount in Box 1 on the 1098-T.

If I can't send until I get a corrected form, is it best to file an extension until I receive it?  Thx!
