Home Office deductions for part time job?

For 2019 I will be working full time, in addition to continuing as independent-contractor with home office (employed for company X, and, independent-contractor part time for company Y at the same time). I expect to receive a W2 and a 1099-MISC for 2019. So, I'm asking for figuring out my estimated 2019 taxes and planning for 2019 expenses. Will home office still be a write off for independent contracting? Is there a minimum of how many hours or 1099-MISC income is needed to have the home office expenses write off?  (Note, this question is the home office for independent contracting only, I understand the distinction for a requirements to write off home office as an employee and that would not apply to my case)
