Deductions & credits

No, trying to figure it out.  The IRS changed income level but didn't state why just reduced refund, which should have been all of our withheld federal tax, but was about 2/3 of it.  Also the program did not show carry over for the amoun of charitable deduction that wasn't used, since we had other items on schedule A.  I need to get tech support, probably me, not the program but don't know who to correct it.
