new rules for 4a and 4b are written as if the writer were writing for two separate lines and did not expect that someone could rollover and then convert funds from 401(k)--->trad IRA --->Roth IRA in the same year.
Question is that if you follow rules then rollover and conversion of the same 401(k) funds you end up putting the same numbers twice in 4a (one for rollover and again for conversion). Basically, you will repeat it twice just because the previous two line (15 and 16) now became one line 4. But it makes no sense.
so, again, two 401(k) got rolled over into IRA (15,000 and 20,000) and then one of them, 15,000, got converted to roth IRA. what number goes to 4a and what number goes 4b? do you put 15+20=35 on 4a or 15+20+[15]=50?
