Interest expense limitation

I am a self-employed (graphic designer) and some interest due to some investment in expensive hardware. 

 

It's not really clear for me if there is a limitation or not? 

 

I found in the IRS documentation that : 

 

"The business interest expense deduction allowed for a tax year is generally limited to the sum of:

1. Business interest income,

2. 30% of the adjustable taxable income, and

3. Floor plan financing interest."

 

But I'm not sure if Turbotax handles it automatically or if I should be careful of that?
