Retirement tax questions

I deleted the imported form 1099-R and re-entered it and went through all the questions.  That all looks good but there is still nothing populating on lines 6, 7 or 12 of the Form 8606 yet on page 2 of the Form 8606 line 15a the figure is correct which is subtracting line 12 from line 7??  I am so confused.  The calculations are all correct.  Should I file the return with lines 6 & 7 being blank since everything else is correct?  I'm not sure what other option I have?
