Get your taxes done using TurboTax

Need additional help with this one... So I filed my return allocating 100% .  I forgot to include the 1095-A info on my older son's return so his got rejected.  Do I need to fill in all months on his return even though he was only covered January - May?  Or do I just enter the January-May months and allocate 0% on his return.  It works out better to actually allocate 100% on mine.  Thanks for any help!
