How to find files with a specific pattern in the parent and child directory of my present working directory using a single command ?

Filename - test.txt, the file has the pattern "nslookup"

This file is present in 3 directories and they are /home, /home/1 and /home/1/2

I am currently at /home/1. I have tried below commands :

find ../ -type f -name "test.txt"

Output :

../test.txt

../home/1/test.txt

../home/1/2/test.txt

I was able to find the files, hence I tried the below command :

$ find ../ -type f -exec grep "nslookup" {} ;

nslookup

nslookup

nslookup

This doesn't display the file names.

Command : find . -type f -name "test.txt | xargs grep "nslookup' ==> gives me files in pwd and child directories :

./1/test.txt:nslookup

./test.txt:nslookup

but when I try to search in the parent directory as shown below the results are erroneous :

find ../ -type f -name "test.txt" | xargs grep "nslookup
