R&D Credit Form 6765

[Debbie CPA]

Line 29 asks to enter qualified research expenses for 3 prior tax years

No help in instructions.  Surely this can't mean to report expenses claimed in prior years??

[IntuitCharlene]

The government instructions give a bit more of an expanded description: 

Line 29
Enter your qualified research expenses for the prior 3 tax
years. If the credit terminates during the tax year, prorate the
qualified research expenses for the prior 3 tax years for the
number of days the credit applied during the tax year.
