I will be self-employed for 2020 but will also be working a part-time job, doing the same type of job. Will I still be able to deduct my home office expenses?

My freelance job is the same as my part-time work.

If your home office is used regularly and exclusively and is your principal place of business for your self-employment work, then you would qualify to take the home office deduction with your Schedule C business.  

To be considered exclusive to the Schedule C business, you should not be using the same space as a home office for your part-time job.  

Take a look at the following TurboTax article for more information:  Can I take the home office deduction?

I think you are saying you use the same home office for both a W-2 job and your self employment.  Yes, you may deduct a portion of the home office.  W-2 employees are not allowed to deduct home office expenses.  So, for example, during the year you worked 500  hours, in the home office, on your W-2 job and 1500 hours on your self employed work, you may deduct 75% (1500 / 2000) of the home office cost on Schedule C.

I'm of the opinion that "regularly and exclusively" means for paid work and is not limited to your self employment. It does not matter if the work is similar, on the two jobs.
