Retirement tax questions

I've taken distributions for many years now, as an old person.  It asks for the amount of distribution and says do not include the amount that was a QCD, so i have to consider it.  They put a number there that does not correspond with either my whole distribution or anything like it.  So i want to know where it came from.  ie. i took $8000 distribution, of which $5000 was QCD.  But they write i took a $10,000 distribution.  So i have no idea why.
