How to set up tabs in Webstorm?

Question

webstorm

Hello. Help solve this problem.
In webstorm, stylus files contain tabs. When executing Reformat Code, everything becomes as it should.
But if I press enter on a new line

.form-search
  .form-group__btn
    margin-bottom 0

Вот здесь

Then when transferring to the next line, it will immediately indent 4 spaces. It is spaces and not 1 tab.
I have this situation with only 1 file. How can this be fixed? Thanks in advance.
Is it possible for it to not add padding at all?
