Roth conversion

My husband and I both have amounts that we converted from traditional IRAs to Roths.  The amounts were $40,000 from the IRA with $4800 held out for Fed taxes and an odd amount of $35,598.32 from a different IRA with $4,271.80 taken out for Fed taxes.  Are the amounts of $4800 and $4271.80 taxable since they were taken from the IRA but not part of the Roth conversion?  How do I record this?  Please if you can walk me through this step by step I would appreciate it.  I have used Turbotax for years without any difficulties but this is just not going through correctly somehow.
