Can I use the "taxpackagesupport" K-1 as is?

These don't have all the entries that are on the paper K-1s I receive in the mail.  For example, they don't contain the line 20, code ZZ (other) entries.  These are the entries I am most interested in asking about, as these line 20, code ZZ entries are the most time consuming entries for each of my K-1s.  Are they really necessary?  If so, is there any way other  than just manually typing them to get them into Turbotax?

It all depends on the information reported on your Schedule K-1, line 20, code ZZ. It could be something that affects your tax return. You want to at least make sure that the code doesn't reflect information that could affect the tax return. 

Usually, if code ZZ has information that could affect your tax return or your basis, that information will need to be manually entered in another (appropriate) part of the tax return.
