The availability of the software 1040X changed to March 18---less than a week from today. I recommend waiting for it.
The 1040X will not be available in the software until March 18 You are correct that the the paper form is on the IRS site. You can print out that 1040X form if you want to use it—-and prepare your amended return by hand to mail in instead of waiting to use the software and e-file it.

You can expect it to take 4-6 months for the IRS to process your amended return.
