Basis on form 7203 is wrong-can I adjust without looking bad?

Turbotax says my basis in my S Corp is over $49,000 on form 7203, but really my business bank account had only a few thousand dollars at year end.  Somehow Turbotax did not record the distributions I entered the last few years.  If I adjust the basis to only a few thousand dollars, will that flag something bad to the IRS?
