Just a note since this Question is a few years old: there's a quicker and easier option for men who have taken an AncestryDNA autosomal test (or MyHeritage) to obtain a predicted Y-haplogroup: https://cladefinder.yseq.net/. That's operated by the respected Thomas Krahn, CEO of YSEQ and one of the designers, back in the day, of the lab in Houston that Family Tree DNA uses.
Joseph, I don't see on your profile yet that you've added that "Other Y-DNA" test. One sort of tricky step is that it may not be completely clear there is a final step to save the information after you've entered it.
Step two would be to begin filling out your own lines starting with your parents. WikiTree can't do any actual DNA analysis because it stores no DNA results. It only knows that you've taken a test, and the info you supply along with entering that test onto your own profile.
It takes a day or two for the information to propagate around the tree, but it can only distribute as far as your own connections go. In the case of your yDNA, that's your patrilineal line...which also includes those ancestors' male children and their male descendants. So yDNA can spread pretty far into a lot of "DNA Connections" panels if your line is broadly connected in the tree. But it won't go anywhere at all unless you have some of that patrilineal line filled out.
It would be very interesting to see what that Cladefinder option shows as a predicted haplogroup. N-M46 is very, very old--somewhere around 15,800 and 11,900 years old, in fact--and it doesn't correspond to the deeper, old-style nomenclature of N1c1a1a1a. In fact, even the 2019-2020 ISOGG Haplotree has no designation for a N1c branch at all.
The N-M46 SNP (single nucleotide polymorphism) is now more commonly shown on haplotrees as "N-TAT." An older Project at FTDNA, "N1c1 Haplogroup" indicates that a defining marker for N1c1 at that time was N-M178.
N-M178 now displays as N1a1a at ISOGG. So adding N-M46 as your haplogroup probably won't help; there's clearly been a restructuring at a deep level of the basal N haplotree since the Morley DNA Predictor was written some six or more years ago.
If I were you, I'd give a run at Cladefinder to see if you can obtain more useful information to add to that "Other Y-DNA" test on your profile.
