I am aware that people speak in past simple tense when they use a finished time words (last year, last month, in 1805, etc.).
I also understand that, when the sentence is in present perfect, you cannot use those words; you can only use UNFINISHED time words (today, this week, this month, etc.).
My question is: can you use the past perfect tense with an unfinished time words, as in,
A: Have you been to New York?
B: Yes, I had been there last year.
Or something similar along the lines of "had been to (a place) last year".
Please note that it is NOT "...by last year" or "...until last year"; it's just "... last year".
