Which form do i file to dissolve? I'm reporting using a 1065, but the entity is an LLC.?

also re remaining ets. i wanna dissolve say tomorrow, and we've distributed everything out. but we've got one last check coming in the mail. will that be a problem? can't i just proceed and when the check comes deposit it and pull it our pursuant to the distribution? we already ped a resolution choosing the 28th as our last day. what if our check doesn't come by then? or can i just wait to file until the check clears and is distributed out? btw..thanks tax lady and others for your great answers. it's more help than you think!!! and i've got CPA friends that are helping too but yahoo answers is such a great tool...
