Hey there!
I would suggest doing these entries as records vs. columns in its own Hours table.
Use a Text field as the Primary field and input January, February, etc. as the records. (you could also use Date as the Primary if you want to get more granular)
Add a Single-select field and add the 2022 year to every record
Add a Numbers field for the Hours
Then create a linked record to the Projects table
You might also consider using January 2022, February 2022, etc in addition to having a Year field. Sometimes filtering and grouping can get confusing.
