GE Aerospace Stock Cost Basis after GE Vernova Spin-off?

Anyone know how or where to find the cost basis of what used to be 
called 'General Electric' which no longer exists?

Background: That company ("GE") has legally changed its name to "GE 
Aerospace" and it spun off its power systems unit to a new corporation 
called 'GE Vernova' effective 4/2/2024, stock symbol "GEV".  (GE 
Aerospace kept the old 'GE' symbol).
