I don't use LTspice but you add Spice directives from the menu - "Add Spice Directive" or hit the letter S. Then add the mutual coupling you want e.g. k1 l1 l2 0.8.

Re: LTSPICE error message - mutual inductance card missing coupled inductor

WebSPICE does not allow to connect a voltage source in parallel with an inductor, as it thinks that the voltage source is short circuited. You can place a small resistor (ex. 0.001 Ohm) in series with the voltage source to overcome this problem. Back to Spice Guidelines.
