I interpret this as being a $3,144 distribution from some kind of retirement account, maybe an IRA, and an independent new contribution of $7,000 to an IRA. As it stands, no, the $7,000 deposit is not a rollover of any part of the $3,144 distribution.
If the $7,000 deposit was not made within the 60 days following the receipt of the $3,144, nothing can be done to change any part of the $7,000 to be a rollover of any part of the $3,144. However, if the $7,000 deposit was made within those 60 days, you can potentially contact Fidelity to correct the record of the $7,000 deposit to show that it was a rollover of $3,144 plus a new contribution of $3,856, if it's of any benefit for you to do so.
