How to add my income without a T4 slip? There is no selection about that. I couldn't get T4 slip from one of my previous employer. He doesn't answering phone or mail.

If your employer has not provided you with a T4 slip, check your CRA My Account to see if the slip has been sent to CRA. If you are not a CRA My Account holder, contact CRA directly to find out if a T4 has been issued to you.

If no T4 has been issued to you, you can use your pay stubs or statements to estimate the income to report and any related deductions and credits you can claim as if a T4 was issued. Here's a link from CRA for more information: https://www.canada.ca/en/revenue-agency/services/tax/individuals/topics/about-your-tax-return/tax-re...
