Retirement tax questions

I have no “basis”. The 8606s ran down to -0- in 2016. Everything left in my IRA is taxable.  I have made no non-deductible contributions nor ANY contributions. 

TT still will not enter the $25,000 cash distribution as taxable (not showing on Line 4b) but it is rightly taxing the $100,000 ROTH conversion (shows on Line 4b) and 8606 Part II. PART I is blank but I think therein lies my problem but someone else said “no”. 

If you have any other ideas I would welcome them. Thank you.
