For default value too, try these:
SELECT object_definition(default_object_id) AS definition FROM sys.columns WHERE name ='colname' AND object_id = object_id('dbo.tablename')or linking to the column explicitly:
LEFT OUTER JOIN sys.default_constraints dc ON dc.parent_column_id = c.column_idhttps://docs.microsoft.com/en-us/sql/t-sql/functions/object-definition-transact-sql?view=sql-server-2017
