I overestimated my income for obamacare, shouldn't I get a PTC refund?

I overestimated my income for obamacare and I paid my obamacare premiums in full, received no PTC.  

TT indicates on the 8962 for that my % of FPL is 377%.  As a results, shouldn't I get a small PTC refund when I reconcile this in my tax return?  TT indicates I do not quality for PTC, 0 amount allowed.

I should add this info...I retired in 2017.  I had company insurance through May, 2017.  I signed up for obamacare for June - December and paid full premium cost for that.  My final year-end income was lower than I thought, and put me in what I thought now should be eligible for PTC cause of the calculated FPL of 377%.
