Not able to show Income Tax in salary slip

In new versions where we have segregate salary slip into different tabs like details, earnings and deductions etc. I am not able to see Income tax. Do I need to do some specific settings??

Income Tax should be part of Deductions as a Salary Component (Eg: TDS etc)

Yes it was coming earlier as a part of deductions but after taking latest of ERP it is not coming. When I check their version history and pull request I found they have segregate the tabs and now we have a separate tab for named Income tax breakup. I am not getting that too.
For reference : feat: display tax break up on salary slip #267

In new version I am getting like this

No Income tax breakup tab and no TDS in deductions. Am I missing something? Please guide
