Is it true that if we use Turbotax desktop version of premier - we can not efile crypto currency related gains/loss?

Somewhere on this forum I read that for crypto currency transaction one must have online version of premier TT

so we can use desktop version for crypt related transactions?

and for desktop version we can have 5 federal efile included(whole family)  vs online you have only one efile (one person?)

 

If 5 efile - can we efile for a friend or he/she must be a blood relative ?
