Do I file 6251 for AMT FTC 1116 carryover credits if I'm not subject to AMT?

I'm not subject to AMT so the instructions says not to file form 6251.

I want to carryover AMT FTC, so I assume I need to file AMT 1116

However, instructions for AMT FTC says to attach AMT 1116 behind 6251.

So should 1:

1. not file 6251, and attach AMT 1116 to the end of the return or the normal sequence?
2. file 6251 in the normal sequence, and attached AMT 1116 behind it?
3. attach 6251 to the end of the return marked "do not process", and attach AMT 1116 behind it?
