Taxes for 2019

 

Hello,

I have some fears about my taxes for 2019, it's the first time I owed and don't want to make the same mistake so this is what I did:

 

1-I have 2 jobs that I work from home (W-4) in one I have them take off my taxes with exceptions since I am married and have a kid and the second one I claim 0 exceptions, would that help me not to owe to the IRS?

 

2- Also my wife is a freelance makeup artist, she goes to different sites as well as she has a home office/studio, can either her or myself claim deductions about working from home?

 

3- I recently download the Quickbooks self employed app for her and her tax deductions , what are the deductions that she can do in her position?

 

I hope someone helps me.

 

Thanks in advance.
