Is a transfer of funds from a TSP account to a traditional IRA considered a contribution to the traditional IRA?

No, it is not a contribution.   Contributions are very limited, $$-wise, as to how much can be "Contributed"..... A direct-transfer, or a rollover from a TSP account to an IRA is not $$-limited.

IF a 1099-R is issued for that transfer, you enter it as a distribution in the software, and the follow-up questions vary depending on exactly what codes are in box 7. 

IF box 7 contains a letter "G", that indicates a direct-transfer, and you just need to indicate in the follow-up questions whether it went into any kind of ROTH account...if it didn't go into a ROTH account, then a Traditional IRA is assumed.

IF box 7 is some other number, then they issued a check, and in the follow-up questions you need to indicate that it went into another retirement account, and then exactly how much went into the IRA (because some people keep some of the $$ and don't put it all back into the IRA, and also any withholding kept on distribution did not end up in the new IRA unless YOU made up the difference)
