I took a volume lash course in 2018 how/where do I enter that? Also what happens if I do not know one of my children's SIN?

I am a certified esthetician. I have started taking courses to be properly certified in the things that have changed since I became certified. I took a volume lash extension course last year that cost around $800. How and where do I enter this?

Vocational training can qualify for Tuition credit, but you require an official tax receipt for income tax purposes. 

Regarding child’s SIN, you don’t need to enter it on your return. 

The SIN would be needed only if the child has to file a return, for income reasons.
