Is paying back paid-in capital taxable income to me?

I'm a single member LLC taxed as an s-corp as of 1/1/22.

All income this year was used to build a free-standing office building.

Since the income alone was not enough to cover the cost, I put personal money into the business to cover the extra cost for it.

As such, I didn't pay myself any salary as any income was also used to build the office building.

And I still have paid-in capital invested I would like to be paid back for. 

 

Question 1: Is it ok that I didn't pay myself salary all year since I used all income to build the office?

Question 2: Does the fact that the office building have to be depreciated over 39 years make me owe taxes on the business income, even though I couldn't pay myself anything? 

Question 3: If in 2023, I pay myself back from paid-in capital,  are those payments tax free and not considered distribution? What would those payments be called?

 

Thank you so much for your time!!
