Previously self-employed but not anymore

I have used the turbotax self-employed online program for the last several years having both full-time employment as well as independent contracting.  I am no longer an independent contractor but I still filled used the turbotax self-employed program this year and as I am getting ready to file I'm not sure that was the right program to use.  I seem to owe an awful lot more this year but my income hasn't changed very much.  I itemized deductions before but went for the standardized deduction this year since I am not independently contracting.  I'm not sure I went for the right deduction.  Can anyone advise?
