That depends largely on the IRS, who issued the guidance only a week and a half or so ago. You'll have to wait. this isn't a software problem, it's a tax law problem and it will take a little time to resolve. It isn't known exactly, or it would tell you that, but there is no workaround.
It is relevant that the IRS isn't accepting returns - that means that submitting yours sooner than that date won't help since they're not processing them anyway.
