Adding a column in multiple tsv file using awk

Question

I have two subdirectories named "Sample" and "Price". "Sample" consists one file named "1.tsv" while "Price" consists of >10000 tsv files named A.tsv, B.tsv....and so on. I want to insert the 1.tsv into every file present in the "Price" directory before the first column.

Sample file in "Sample" folder: 1.tsv

Name	ID
Samul	25
Alex	36
RDXC	14
Plut	38

Sample file in "Price" folder: A.tsv

Name	ID
Rajn	39
Maxo	05
DNDT	11
Maxi	21

Sample file in "Price" folder: B.tsv

Name	ID
Cars	98
Lint	20
Marq	45
DNSA	17

and then c.tsv, d.tsv......etc

Output file: 1.tsv and A.tsv

Name	ID	Name	ID
Samul	25	Rajn	39
Alex	36	Maxo	05
RDXC	14	DNDT	11
Plut	38	Maxi	21

Output file: 1.tsv and B.tsv

Name	ID	Name	ID
Samul	25	Cars	98
Alex	36	Lint	20
RDXC	14	Marq	45
Plut	38	DNSA	17

and same with other files like 1.tsv and c.tsv, 1.tsv and d.tsv.......so on. This is sample data, in reality, each file has around 56000 raws. Thank you in advance.
