Use a custom group to groupby like below:

# Input data
>>> df

              0
0      Payment 
1    Chq 102100
2  Payment Bank
3       Payment
4    Chq 123000

# Output result
>>> df[0].str.strip() \
         .groupby(df[0].str.contains('^Payment').cumsum()) \
         .agg(' '.join).to_frame()

                    0
0                    
1  Payment Chq 102100
2        Payment Bank
3  Payment Chq 123000
