If someone has been praying in the wrong qiblah direction (wrong by about 90degrees) for many years, do they have to pray qadha for all those prayers?

This mistake started from when we moved into a new house in 2012 and our father had determined the qiblah for us. Only a few days ago did I check again and noticed we were mistaken.

If it within 180 degrees either way then it is still fine
If it was completely opposite then prayers would have to be repeated.
