Hi Terie,
When you search for a ZCTA, the dropdown menu shows results for both ZCTAs and ZIP codes:
Is it possible you clicked on the ZIP code instead of the ZCTA? There isn't ACS data for ZIP codes (which are not technically areal units, just a collection of mail delivery locations), but there is for ZCTAs (which are made to approximate ZIP codes).
By the way, I don't know why it shows the same ZCTA twice. That makes me suspicious that one of them might work and the other might not for a given ACS year.
