Deductions & credits

software never asked me to enter in any tips for deductions. 

I'm unable to find any deduction mentioning/referencing tips to enter.

Again, is this an issue with the web based system and is not available or do I need to purchase the software for it have this feature?

As stated I have gone through it time and time again and at no point does the web based version ask me to enter in anything for tips for deductions.
