Form 7203

My business's CPA gave me a Schedule K-1 with a completed 7203.  The CPA's 7203 includes a figure for line 8a.  Turbotax, however, will not allow me to enter that information in line 8a.  As a result, my share holder basis, line 15 is wrong in turbotax.  It looks like my only option is to hire a CPA so or complete my taxes by hand.  Is that right?  I must enter this figure, and TurboTax does not allow me to do so.
