Retirement tax questions

I'm chiming back in.  Could this be an issue?  I had an RMD last year, a routine withdrawal, but I misplaced the 1099-R and didn't include it in my tax filing in the spring.  I discovered the 1099-R and amended my Turbotax filing in August to include it.  Could this now be confusing the program somehow?  It thinks it sees two RMDs since last April?
