Yes use "various". What is the worst possible scenario? You get an IRS letter requesting you specify exactly what countries they are. You write back that TT had a software issue and send a letter back breaking the countries out or simply modify Form1116. At this point what else can you do? I don't think you can modify the form by overriding/adding anything as TT may reject your E-filing your return. Or you can just use "various" have TT complete the form, then you can do your own modified form that specifies the countries. HOWEVER you will then have to file manually.
