My wife and i were separated for about 7 months in early 2017 and 1 of my kids lived with me. how do i fill this in now that my wife and i have reconciled late in 2017?

You need to claim married as you were and are as of Dec.31/2017. By preparing a coupled return, information can easily be entered on both returns, maximizing your deductions and credits. This way the software will advise who should claim the children for maximum credits.
