Why I suggest always using desktop version of TT, you can drill down and enter forms mode to see where a problem is....  Most superusers would never using online TT, there is always something where you want to be able to see the calculation.  (so you saw all the screen shots below areas and clicked each individually, you didn't put an amount in the question about other income within that section....).
**I don't work for TT. Just trying to help. All the best.
