Essentially, forced bulbs bloom and then go into dormancy, missing the part where they spend the summer storing energy. The best you can do is store them, as you would store any spring flowering bulb, until its time to plant. Store them cool and dry - for me, that's in a paper bag in the crisper drawer of my refrigerator.
Forced bulbs don't perform well ever again. The tulips most likely won't flower at all. The daffodils have a chance but it may take a couple years. When you plant next fall, add some bulb food to help them along.
