Business & farm

I have the "DISC" version of TURBOTAX "PREMIER" and "BUSINESS".  The PREMIER version has allowed me to create a SCH-C for my OIL/GAS BUSINESS (new for me this year).  I thought that I would need to upgrade to "SMALL BUSINESS" version but maybe not.    I am also curious where to input my "INTANGBLE DRILLING COSTS" data provided by the drilling company on my invoices.   I read that "INTANGIBLE" drilling costs my be taken in full or depreciated over 7 years.  I also hear that the "TANGIBLE" drilling costs must be depreciated over 7 years, but again I'm not sure where to enter that data either.
