Once re-potted and brought back into the warmth and light, hippeastrum bulbs should begin to bloom, or begin to grow scapes, after about 6 to 8 weeks...

I'd like to see what others think, but my opinion is that perhaps your bulbs didn't get to properly recharge before you put them to sleep... they should be spending all summer outdoors, from the time frost is no longer a danger in spring, until about 16 weeks prior to the time you want flowers. So, typically, you would put them outdoors and feed and water them regularly, making sure they got plenty of sunshine, until the latter part of August... if you want flowers for Christmas. Then, you'd place them in a dark unheated, but frost-free, garage or basement and withhold water for the next 6-8 weeks... then, you'd bring them into your home once again, trim off the dead growth, re-pot and water, place them in a bright, warm spot... and within 6-8 weeks, you'd see signs that they were going to flower...

What does everyone think?

"stored in basement over summer"...

The bulbs should have been kept green with leaves, fertilized and given lots of light during summer, and they should only have been let go dormant from September or so. It seems like that your bulbs will not be able to bloom because they were starved during the time they should have recharged. Also, fertilizer is not necessary and can even be detrimental to the roots until the bulbs are not growing green leaves actively.

You can still save them for next year. Just keep them green, well fertilized and definitely NOT overwatered in a warm, light place during summer. If you have the opportunity, you can even plant them out. Then only let they dry out from September. Not earlier... They need that time to recharge. And they might give you flower for next year.
